I have switched but have not received my key and/or card yet, how do I top up?

Continue to top up as usual with your current key and/or card until you receive your Nabuh key and/or card. On receipt of the new key and/or card ensure all current credit is run down to Zero before inserting your Nabuh key and/or card to register it, if you insert the card before the credit is at Zero any current credit will be lost. Once the key and/or card is registered top up at your local place of vend as you did before.
